In this section, you’ll learn how to copy a file into lakeFS.

Configuring the AWS CLI

Since lakeFS exposes an S3-compatible API, you can use the AWS CLI to operate on it.

1. If you don’t have the AWS CLI installed, follow the instructions here.

2. Configure a new connection profile using the lakeFS credentials you have generated earlier:

   aws configure --profile local
   # fill in the lakeFS credentials generated earlier:
   # AWS Access Key ID [None]: AKIAJVHTOKZWGCD2QQYQ
   # AWS Secret Access Key [None]: ****************************************
   # Default region name [None]:
   # Default output format [None]:
   

3. Let’s test it to check whether it works. You can do that by calling s3 ls, which should list your repositories:

   aws --endpoint-url=http://localhost:8000 --profile local s3 ls
   # output:
   # 2021-06-15 13:43:03 example-repo
   

   Note the usage of the --endpoint-url flag, which tells the AWS CLI to connect to lakeFS instead of AWS S3.

4. Great, now let’s copy some files. You will write to the main branch. This is done by prefixing the path with the name of the branch we’d like to read/write from:

   aws --endpoint-url=http://localhost:8000 --profile local s3 cp ./foo.txt s3://example-repo/main/
   # output:
   # upload: ./foo.txt to s3://example-repo/main/foo.txt
   

5. Back in the lakeFS UI, you can see your file in the Uncommitted Changes tab:

It’s time to commit your changes using the lakeFS CLI.
